How would a volcano erupting cause global climate changes?

Answer 1

A volcano erupting can have a cooling effect. By putting a lot of dust in the upper atmosphere and reflecting sunlight. This happened fairly recently. Krakatoa blew up in the 1880s and some of the coldest winters on record are 1888-89. A lot of those records still stand today. There are many variables involved with the climate on our planet.

A volcanic eruption can have only a very slight, imperceptible effect on the level of atmospheric carbon dioxide and consequently on global warming. For example, the volcano that erupted in Iceland in 2010 vented between 150,000 and 300,000 tonnes of carbon dioxide per day. This is minuscule compared to emissions from burning fossil fuels, of around 30 billion tonnes per year.

Answer 2

When very large volcanoes erupt a lot of smoke and ash pollute the air. Usually its very warm so when it rises up above over the city it becomes a bit warmer. Also if the lava and magma flow to many places it can heat the ground and it can spread throughtout the area of eruption. Hope this helps :D

Answer 3

because the put so much ash into the atmosphere that it can block out the sun and cause nuclear winter. ( this is the reason the dinosaurs died because all the plants died because there was no sunlight)

Answer 4

Volcanoes often release gasses when they erupt. Sulfur compounds usually have the greatest effect. A massive eruption, such as the Tambora eruption of 1815, can sent a plume of gas and ash into the stratosphere. The sulfur compounds can stay there for years. reducing the amount of sunligh that reaches the earth's surface and lowering global temperatures.

Answer 5

When a volcano erupts, it releases large amounts of ash, gases, and particles into the atmosphere. These particles can reflect sunlight back into space, leading to a temporary cooling effect on the Earth's surface. Additionally, volcanic gases like sulfur dioxide can react with water vapor to form sulfuric acid aerosols, which can contribute to further cooling by enhancing cloud formation.
